Dr. Silvano Senn is a Dentist. He is a good friend of Rowen. Rowen asked Dr. Senn to be the “demo” at Rowen’s Ozone Training Workshop, where Rowen would inject the “demo” person with Ozone for a Prostate Issue. Dr. Senn did not have a Prostate Issue. Rowen just needed someone to be the demo person to show the students in the class how to administer this type of injection into a man’s Scrotum. In this video, Rowen and Dr. Senn are hiking together, and Rowen has Dr. Senn tell his story, how that “demo” Ozone injection into his Prostate had a positive effect on his male sexual function with his wife.
